Publication number: 20140272477Abstract: Disclosed herein are systems, devices, and methods for a hybrid electrochemical cell which utilizes two different chemistries in the same cell. According to one aspect, the hybrid cell includes a first pair of electrode units which form a first electrochemical cell and a second pair of electrode units, which form a second electrochemical cell. The second electrochemical cell utilizes a different chemistry than the first electrochemical cells, but both chemistries share a common electrolyte. The hybrid cell further comprises a common electrolyte layer provided between each pair of electrodes. In certain implementations, the common electrolyte layer is a single cavity such that the electrolyte is shared between both the first and the second electrochemical cell.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: G4 Synergetics, Inc.Inventors: Jon K.

Publication number: 20140194870Abstract: Bipolar electrosurgical forceps are provided with dual irrigating tubes that deliver irrigating liquid to the opposed surfaces of the tips of the forceps to prevent the sticking of body tissue to the tips. To reduce the manufacturing costs of the forceps and enable the forceps to be single use, disposable forceps, each tube of the dual irrigating tools is a plastic tube adhered along one of the opposing surfaces of the pair of forceps arms. Each tube also has a flat nozzle at the distal end of the tube that disburses irrigating liquid across the opposed surfaces of the forceps arm distal and tips.Type: ApplicationFiled: January 9, 2013Publication date: July 10, 2014Applicant: Synergetics, Inc.Inventors: Matthew A.

Publication number: 20140121690Abstract: A microsurgical instrument has a pair of operative surgical surfaces that are moved relative to each other in shearing or grasping procedures performed by the instrument. The instrument has a handle containing an elongate center rod with a ring mounted for reciprocating movement on the rod. A tube is secured to the ring and a shaft extends through the tube and is secured to the rod. The handle also includes a plurality of resilient arms that extend along the length of the rod and engage against a sliding surface of the ring on the rod. The plurality of actuator arms are alternatively manually compressed radially inwardly by the surgeon's hand and released by the surgeon's hand to allow the arms to flex radially inwardly and outwardly. The inward and outward movement of the plurality of arms reciprocates the ring on the handle rod and causes the tube and shaft to move axially relative to each other.Type: ApplicationFiled: November 12, 2013Publication date: May 1, 2014Applicant: Synergetics, Inc.Inventors: Matthew A.

Patent number: 8632901Abstract: A stacked battery has at least two cell segments arranged in a stack. Each cell segment may have a first electrode unit having a first active material electrode, a second electrode unit having a second active material electrode, and an electrolyte layer between the active material electrodes. One or more gaskets may be included in each cell segment to seal the electrolyte within the cell segment. The electrode units may be “dish shaped” and may contain a pressure equalization valve to reduce electrode unit deflection and improve pressure equalization between cell segments. The pressure equalization valve may allow a gas to diffuse through adjacent cell segments and may substantially prevent electrolyte from diffusing through.Type: GrantFiled: October 27, 2008Date of Patent: January 21, 2014Assignee: G4 Synergetics, Inc.Inventors: Jon Kenneth West, Martin Patrick Higgins, Julius Regalado, Anthony George

Patent number: 8496681Abstract: A system for conducting a vitrectomy includes: a gas source; a vitrector including a cutting mechanism that opens and closes according to a pressure at the vitrector; and a pulse-generating system receiving gas from the gas source and generating pulses at the vitrector. The pulses cause the pressure at the vitrector to vary according to a cycle, and the varying pressure at the vitrector causes the cutting mechanism of the vitrector to open and close. At a first time in the cycle, the pulse-generating system, raises the pressure at the vitrector to a maximum pressure. At a second time in the cycle, the pulse-generating system reduces the pressure at the vitrector to a minimum pressure that is greater than ambient, the pressure at the vitrector being maintained at least at the minimum pressure. The difference between the maximum pressure and minimum pressure is minimized to reduce gas consumption.Type: GrantFiled: June 6, 2011Date of Patent: July 30, 2013Assignee: Synergetics, Inc.Inventor: James C. Easley

Patent number: 8197468Abstract: A surgical instrument handle is removably attachable to a surgical instrument head for operation of a microsurgical instrument on the head by manipulation of the instrument handle. The instrument handle has an elongate center rod with a piston mounted on the rod for reciprocating movement. The piston engages with a piston in the attached surgical instrument head for operation of the microsurgical instrument of the head. A tapered ring is mounted on the rod and engages with the piston for reciprocating the piston. A plurality of resilient arms extend along the length of the rod and engage against a sliding surface of the ring. The plurality of resilient arms are alternatively squeezed radially inwardly by the surgeon's hand and released by the surgeon's hand to allow the resilient arms to flex radially outwardly. The inward and outward movement of the plurality of arms reciprocates the piston on the handle rod to cause operation of the surgical instrument head.Type: GrantFiled: November 15, 2004Date of Patent: June 12, 2012Assignee: Synergetics, Inc.Inventors: Gregg D.
